The Alyeska Climbathon is a multi-lap, all day event held on the North Face Hiking Trail at Alyeska Ski Resort. Participants ascend the approximately 2.5 mile hiking trail that gains 2,000 vertical feet from the Hotel Alyeska to the top terminal of the Alyeska Aerial Tram.
A lap begins at the tram base, climbs the North Face Trail and is counted at the top of the tram. Participants descend the tram and repeat over and over.
Over the course of 10 hours, participants lap the trail as many times as physically possible. It is a non timed event. The winner of the event makes the most laps in the event.
